Abstract (en)

There is provided methods and apparatus of encoding/decoding into/from a bitstream, geometry of point cloud frames of a point cloud sequence. Methods use an inter Trisoup coding/decoding scheme, i.e. a scheme that encodes/decodes Trisoup information of a current point cloud frame of the point cloud sequence by making use of Trisoup information of already encoded/decoded point cloud frames of said point cloud sequence.
